features of construction. Fig. 3 is a vertical cross-section takenthrough Fig. 2. Fig. 4 is a detail horizontal sectional view, taken onthe line x-, Fig. 3. Fig. 5 is a detail horizontal sectional view, takenon the line y-fy, Fig. 3. Fig. 6 is a detail sectional vview showing thedetachable connection between the lower stationary member and the upperrevolving member of the base, and the portion which enters the lower endof the bore of the roll of paper.

Corresponding parts in all the figures are denoted by the same referencecharacters.

Referring to the drawings, 1 designates a horizontal base, which ispreferably constructed of metal and in one piece. in the top of thisbase is provided an annular groove or channel, 2, preferably in acentral raisedportion, as at 3, and a series of balls, 4, are seated inthis channel. A cylindrical stud or pin, 5, projects upwardlynfrom thebase 1, centrally with respect to the series of balls 4 and above thelatter. The stud 5 is in secure connection with the base; the connectionmay be formed by threading the stud in a threaded opening in the base 1,as at 6, or in any other suitable manner.

7 designates a supplementary revolving base, which may consist of ametallic plate, turnably mounted upon the projecting stud 5 and adaptedto support the roll of paper (shown at 8) in vertical position. Thesupporting base 7 bears upon the series of balls 4, its under sideresting thereon, preferably at a central annular downwardly-extendingenlargement, as at 9. From the top of the base-member 7 projects acylindrical extension, 10, surrounding the opening, 11, in the base 7for the stud or pin 5 and also surrounding said stud. This extension 10forms a stud upon the base-member 7, which projects within the bore(shown at 12) of the roll of paper 8 at the bottom, to retain the rollin position. The projecting top-end, 14, of the stud or pin 5, above theextensionstud 10 of the base-member 7, is preferably threaded andcarries a nut or tap, 15, whereby the base-members 7 and 1 aredetachably but operatively' retained together and displacement of theballs 4 either in operation or during transportation of the device isprevented g in lieu o`f the threaded end 14 and tap 15 a permanent headmay be provided upon the stud 5, if desired.

The base-portion of the device, constructed according to my improvementsas above described, provides an effective counter-balance or weightagainst the weight of the roll of aper for retaining the latter in its urig t or vertical position; or, if desired, t e base 1 may be suitablysecured or fastened to a store-counter or other support.

16 designates a standard, which rises from the base 1 at one side therevolving basemember 7. The lower end of this standard may be connectedto the base 1 in any suitable manner, preferably detachable; theconnection may be by threading the lower end, 17, of the standard 16into a threaded opening, 18, in the base 1. The standard preferablyconsists of a metallic cylindrical bar bent at right-angles at its upperend, as at 19, to form a horizontal top arm, 20, projecting above thetop of the roll of paper. At its outer end said arm 2O carries a tubularT-piece, 21, the main cylindrical bore, 22, of which registersvertically with the stud 10 of the base-member 7, while its side bore,23, receives the end of the arm 20. The endpiece 21 may be connectedwith the arm 20 in any suitable manner; for instance its bore 23 may bethreaded upon the end of the arm 20, as at 24.

25 designates the knife or cutter, which is mounted vertically andcarried by the standard 16 it may consist of a metal blade having anouter longitudinal cuttin -edge, 26. The blade 25 is carried by lateraarms, 27 the ends of which embrace the standard 16, as at 28, and have aturning bearing thereon, whereby the blade is pivotally mounted withrelation to the standard and with relation to the roll of paper. Thecutting-blade is sustained in position, and held with its cuttingedgeconstantly bearing against the side of the vertically-mounted roll ofpaper, by means of springs, 29, which may consist of a coil, 30,surrounding the standard 16 and having one end, 31, connected to thestandard and the other end, 32, projecting outwardly and against thecutter-arm 27. The bearing-ends 28 of the arms 27 rest upon the sring-coils 30 and are supported thereby.

he ends 31 of the springs 29 may simply be sprung into retainingrecesses, 33, in the side of the standard 16, and the outer projectingends 32 of the springs may be turned to pass under the cutter-arms 27 asat 34, and angularly bent to provide an upwardly-projecting end, 35,which bears against the side of the arm 27 36 designates a holding-pin,which is slidably inserted in the vertical bore 22 of the standard-end21 and is rovided with a supporting or retaining head or handle, 37. Thedownwardly-projecting cylindrical orl tion, 38, of this pin 36 isreceived by the ore 12 of the roll of paper 8 at the top, and operatesin conjunction with the stud 10 of the revolving base-member 7 (whichsupports and carries the roll of paper) to retain the roll at all timesin vertical operative osition against the tensional bearing of the nifeor cutter 25.

lt will be noted that in the construction of my improved paper-cutter asherein described, the base-portion, standard, cuttingmechanism, andholding-pin are all readily separable'or detachable, for convenience andeconomy in space in aching and transportation, and that, Wh e therevolving basemember 7 is secured in connection with thefiXedbase-member 1 by the pin or stud 5 and its tap or head 15 so thatthe ball-bearing members 4 are retained at all times between the members1 and 7 and so retained during transportation of the device, the members1 and 7 ma be separated or detached and the balls 4 reliaased whendesired.

In the improved multiple vertical-series constrii ction comprised in myinvention, as illtstrated in l ig. 1, intermediate base-members, as at39, are carried by the standard 16 at points between the bottomstandard-carrying base and the top of the standard, and

individual cutter-mechanisms are mounted intermediately of said separatebases. This construction of my invention and improvements enables thecarrying of different rolls 'of paper,'as at 8, in vertical series uponone device; the rolls may be of different sizes, as

shown, and placed so that in the series-arrangement of the rolls thelighter or smaller rolls are respectively above the heavier or largerrolls. The base-member 1 of the bottom standard-carrying base will be,in this multiple construction, relatively larger and heavier, to providea irm rest and proper stability for the vertical series of rolls, andthe intermediate base-members 39 may be relatively of a size adapted tothe size of the rolls they are designed to carry. These intermediatebases 39 are preferably mounted upon and carried by the standard 16 inan a justable and separable or detachable manner, for which purpose theycan be provided with an eye or opening, 40, in their stationary member 1at one side their revolving member 7, corresponding to and receiving thecylindrical standard, a set-screw, as at 41, being provided andprojecting into said opening 40 to engage the standard and secure thebase 39 in its supported position; this adjrstability enables variationin the position of the bases 39 to provide for variable sizes of therolls of paper rsed. In this multiple constriction of' my invention, thestandard 16 is extended vertically with respect to the complete verticalseries of rolls 8, and the intermediate bases 39 may carry a cylindricalpin or sttd, as at 42, projecting downwardly from the bottom of thefixed bottom-member 1 of the base 39 and entering the top portion of thebore 12 of the neXt roll of paper 8 underneath. This pin 42 thrs servesth same office as the top holding-pin 36; it may, if desired, be simplya downward extension of the str d or pin 5 which is carried by thebase-member 1 and upon which the revolving b ase-memb er 7 is turnablymounted. lf the bases 39 are adji sted in variable position, to providefor variable sizes of the rolls of paper i sed, a corresponding adjistment for the crtting-mechanisms may be enabled by providing r pon thestandard a vertical series of the retaining recesses 33 in which theends 31 of' the springs 29 are set. This adjustable The operation andadvantages of myV improvements will be readily understood. Paper-cuttersin which the roll and cutter are horizontally placed have the weight ofthe roll of paper upon the horizontal bearings or aXles at each end,which multiplies and increases friction when the roll is revolved to cut0H a piece of paper. In a cutter constructed according to my invention,the roll of paper and cutter are both placed vertically and no part ofthe weight rests on axles or pivots, the whole weight of the roll beingborne by the horizontal revolving base-member 7 which rests upon anantifriction ball-bearing. The studs or pins entering the respectiveends of the bore of the roll of paper serve merely as retaining devicesfor the roll in its turning movement upon its supporting base; there isonly one l bearing, and that is provided at the bottom anti-frictionball-bearing construction, thus insuring ease of manipulation and aminimum of friction so that very slight power is required to revolve theroll of paper. Convenience and facility in measuring the paper to be cutoff is also Ifacilitated by the vertical position of the roll, and theimproved construction enables the insertion or removal of a roll ofpaper with ease and facility. Mashed or tangled rolls of paper can beeasily used and operated, as no axle or bearing-rod need be forcedthrough the roll in mounting it upright in the cuttingdevice. To inserta roll of paper, it is simply necessary to draw back the springactuatedcutting device and seat the roll with its bottom end upon the revolvingbase-member 7 with the projecting stud l() thereof entering the bore ofthe roll at the bottom, then slide the top holding-pin 36 downwardlyinto the bore of the roll at the top, and then release the cuttingdevice so that its 1Knife-edge will continuously press by sprin tensionagainst the outer surface of the ro l; the edge of the paper can then begrasped to turn the roll and the desired sheet cut od against thecutter-edge. There is no strain on the standard or roll-holding members,as the whole weight of the vertically-mounted roll is upon the bottomrevolving ball-bearing base-member 7.

I do not desire to be understood as limiting myself to the detailconstruction and arrangement of parts as herein shown and described, asit is manifest that variations and modifications therein may be resortedto, in the adaptation of my invention to varying conditions of use,without departing from the spirit and scope of my invention andimprovements. I therefore reserve the right to all such variations andmodifications as properly fall within the scope of my invention and theterms of the following claims.
